Flash Friendly File System (f2fs)

This is great, f2fs has been merged in the 3.8 kernel. I read about f2fs awhile back, and was most interested.

A good overview:

The kernel documentation:

User-space tools:

This looks like the way to go for our ARM pups.

Oh, I didn't realise, f2fs was merged in the 3.6 kernel, according to this: http://www.cnx-software.com/2013/01/15/f2fs-a-new-flash-file-system-for-mobile-devices-elce-2012/ ...that link compares the speed of f2fs versus ext4.
